·AIM:To analyze the systemic diseases and perioperative treatment in elderly cataract patients,in order to improve the safety of the surgery.·METHODS:The clinical data of the 141 cases 161 eyes in cataract patients with age≥75 years old who underwent cataract surgery-related in Sichuan TCM hospital in the 4 years from January 2005 to December 2008 were observed.·RESULTS:Totally 31 cases with systemic disease patients temporarily gave up surgery after first assessment,accounting for 22.0% of the total number of patients.Six cases in 31 patients were discharged due to serious systemic diseases after treatment.ECG monitoring and continuous low flow oxygen were performed in 45 cases during operation.13 cases with high blood pressure.7 cases with OCR(Oculo-Cardiac reflex).2 cases with cough.Postoperative corrected visual acuity:light perception to <0.05 in 5 eyes,accounting for 3.4%;0.05 to <0.3 in 7 eyes,accounting for 4.7%;≥0.3 in 137 eyes,accounting for 91.9%.·CONCLUSION:The patients with the systemic diseases should be strengthened to assess the preoperative factors before cataract surgery.The systemic diseases should be treated and strictly mastered operative indication and surgical contraindication.ECG monitoring and continuous low-flow oxygen are applied to minimize the risk of surgery.Gentle surgery action is taken to avoid the Oculo-Cardiac reflex.Cataract patients with systemic diseases are appropriate to relax the visual requirements,be operated as soon as possible.·
